...You've had a break from WoW, and then think of resubbing to do some pet battles or something. But you uninstalled/deleted all things related to WoW to clear some disk space (only one SSD on my laptop) because you thought that the UI will be an exploded mess anyways so might as well start from scratch.
And then remember that just the other day you were cleaning your windows desktop where was some Rematch.lua file, and you permanently deleted that as well.
Yup. :|
